Paper and paperboard are widely used in packaging products. The material behavior of
paper and paperboard is very complex because different scales need to be considered in …

The response of paper to humidity variations is a complex, inherently multi-scale problem.
The hygroscopic swelling of individual fibres and their interactions within the fibrous network …

Pivotal to efficient optimization of filter media using highly resolved pore-scale computational
fluid dynamics (CFD), is the ability to generate virtual filter geometries with controllable …

The hygro-thermo-expansive response of fibrous networks involves deformation
phenomena at multiple length scales. The moisture or temperature induced expansion of …

The mathematical model developed by Reneker et al.[J. Appl. Phys. 87, 4531 (2000)] and
Yarin et al.[J. Appl. Phys. 89 (5), 3018–3026 (2001)] for modeling filament formation in …

Computational modeling of air filtration is possible by replicating nonwoven nanofibrous
meltblown or electrospun filter media with digital representative geometry. This article …

Extrusion-based fused deposition modeling (FDM) introduces inter-bead pores into dense
materials, which results in part-to-part mechanical property variations, ie, low mechanical …

Cellulose fibers come in a wide range of shapes and sizes. The heterogeneity of the fiber
length, width, wall thickness, curl and external fibrillation is detrimental to the mechanical …

In fibrous paper materials, an exposure to a variation in moisture content causes changes in
the geometrical and mechanical properties. Such changes are strongly affected by the inter …

Abstract Background and Objective Recommendations for the use of face masks to prevent
and protect against the aerosols (≤ 5µm) and respiratory droplet particles (≥ 5µm), which …
